I agree with all previous suggestions, so won't repeat them here. Here is a good review of various basting methods & links to video tutorials:

I also like Sharon Schambers' video on basting:

Another product many people swear by to prevent thread nests on the back of quilts is to use: "Magic Genie" bobbin washers. These are just a flat silicone washer (think like a 1/2" diameter round disc) of flexible but stiff material with a hole in the center. It goes into your bobbin case before you put in the removeable bobbin full of thread. It helps stop the bobbin from over spinning & leaving too much thread unwound in the bobbin case. They can be found online @ quilt shops and even ebay. You would want the regular for a home machine, not the "Long-arm" ones.
